• D

What is the pressure due to the water on the top surface of block Y?

• one quarter of the pressure on X

• the same as the pressure on X

• twice the pressure on X

• four times the pressure on X

The meter shows the depth of the diver below the surface of the water.

State the depth shown on the meter in Figure 3.

State the unit.

State how the pressure of the water on the diver changes as the diver swims down from the surface of the lake.

State why the total pressure on the diver is greater than just the pressure due to the water above the diver.

An aeroplane takes off from the ground.

State two factors that affect the pressure of the atmosphere on the aeroplane as the aeroplane goes higher in the atmosphere.

Tick on the blank.

The meter on the battery charger shows the current supplied to a battery.

The meter on the battery charger is_____.

• an ammeter

• an ohmmeter

• a voltmeter

• a wattmeter

The battery charger supplies a steady current of 2.5A to the battery.

Calculate the charge flowing to the battery in 8 minutes.

Use the equation:

charge = current × time
